Abstract
A SWP source includes an electromagnetic (EM) wave launcher configured to couple EM energy in a desired EM wave mode to a plasma by generating a surface wave on a plasma surface of the EM wave launcher adjacent the plasma. A power coupling system is coupled to the EM wave launcher and configured to provide the EM energy to the EM wave launcher for forming the plasma. A cover plate coupled to the plasma surface of the EM wave launcher protects the EM wave launcher from the plasma.
